OPENING ".WIAGHIIQ'IEIl FOB SHEET METAL.

Application tiled ctober 11, 1922. Serial N10. 598,699.

To all whom t may concern.:

Be itknown that I, CHARLES ALSNAUER, a citizen lof the United States, residing at Farrell, in the count'y of Mercer and'State of Pennsylvania, have invented certain new and useful Improvements in Opening Machines for Sheet Metal, of which the followiner is a specification.

, Illy lrivention consists of an improvement in opening machine for tin plate stickers. In the art of rolling thin sheet metal in packs or multiple layers, there frequently occur stickers, i. e., where two adjacent sheets are stuck together. Ordinarily, these are separated by hand, involving laborious, tedious' and costly operations, as well as' tending to deformation of the sheets.

In my invention, I utilize a air of rolls and a dividingnor separating knlfe, over and under which the stuck sheets are drawn by `the rolls, in the manner hereinafter described.

In the drawings: Fig. 1 is a sectional elevation of the machine on the line II of Fig. 2;

. Fig. 2 is a plan view of themachine;

Figs. 3 and 4 are detail views' showing the.'

actionof the rolls. j

In the drawings, 2 is a supporting frame preferably 'mounted on castors 3 for easy movement over a. floor, and provided with a ta'bh- 4-5, preferably at varying levels, as shon n. At each side of the table are housings 6 6 in which are mounted rolls 7 7,v

a transverse knife bladell fixedly mounted as between the housings, with its sharp edge extending away from the pass and its rear edge spaced away from the rollcontours sufiicient-ly to provide re-entrant clearance for the sheets after separation. A

In operation, a pair of stuck sheets 12--12 are first separated by hand at their edges and suiiiciently far back to admit of insertion over and under the knife ll and in-to the grip of the rolls 7. Thereafter, as the sheets are pushed 'over table 4, which is just below the knife l1, the bite of the rolls will draw the sheets forwardly over the knife blade, effecting ycomplete and rapid separa tion, the two separated sheets passing onwardly between the rolls and out onto the lower receiving table 5 beyond. The action of the rolls on the sheets tends toiatten and smooth any wrinkles or bends leaving the-m in good4 merchandizable condition.

The machine is very simple and cheap in construction` may be used for various sizes of sheets, and'maybe moved around to various pointsin the mill for use on accumu- -lated piles of stickers.

What I claim is:

1. A' separating machine for 'sheet metal' consisting of a pair of rollsand a thin separating knife located immediately in advance of the roll pass.

2. A separating machine for sheet metal consistingof a pair of rolls, means for driving the rolls together, a thin separating .knife having an outwardly directed edge located in advance of the pass of the rolls, and a feeding and receiving table at each side of the rolls respectively.

3. A separating machine for sheet metal consisting of a supporting frame provided A with a table and housingsat each side, a pair of rolls therein, gearing and means for driving the rolls together in opposite directions, and a thin separating knife in advance .of the pass of the rolls and mounted by its ends on the housings.

In testimony whereof I hereunto aix my signature.

CHARLES ALSNAUER.
